Application filed March 23, 1922. Serial No. 546,048.

To all QUILOWZtL may concern:

Be it known that I, CHARLES A. TnUAN, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented a new and useful Improvement in Safe and Vault Doors, of which the following is a specification, reference being hadto the accompanying drawing.

My invention relates particularly to ice is for safes and vaults and similar doors which are intended to be secured against the efforts of burglars to open the doors.

The object of my improvement is to provide a secondary locking mechanism which will automatically make engagement to resist movement of the bolt-carrying bar when it is undertaken to disable the main locking mechanism to such extent as to allow the shifting of the bolt-carrying bar to release the door.

The secondary mechanism includes means whereby an authorized person may release said mechanism.after it has been automatically put into engagement.

In the accompanying drawings,

.F' 11 is a perspective of the base or sup port for the solenoids;

12 is a diagrammatic view showing signal devices associated with the main lock ant. the auxiliary lock.

Referring to said drawings, A is the stationary frame around'the door opening. A

are hinges supporting said door on said frame. A are sockets in the frame, A, which receivethe ends of the main locking bolts. 13 is the body-of the door. B B are the usual edge bars extending along the inner face of the door near its four edges. In the edge bars are bearings, B in which rest the main bolts, B The horizontal bolts, B are long and have both ends resting in bearings, B The short main bolts, B have the outer end resting in said bearings,and the inner end in a hearing, B and said bolts are sup ported by one arm of abell crank, 13, the other arm of the bell-crank being coupled to the adjacent long bolt, B in such manner as to cause the short bolt to retract or move forward when the adjacent long bolt is retracted or moved forward. B is the usual bolt-carrying bar. This is upright and extends across the long main bolts near the outer upright edge bar. (he bar, B is iminovably secured to the long bolts, B by 'means of bolts, B vhereby said bar and said main bolts are made a unitary bolt frame to slide horizontally in the bearlngs, B in the upright edge bars, B in the usual manner. l/Vhen said frame is moved toward the outer edge bar, the outer ends of the long main bolts, B enter the sockets, A and the short bolts, B enter the lower sockets, A of the door frame, in the usual manner. For

unlocking the door, this movement is reversed. The belt frame is to be shifted by. 1 means of a shaft (not shown) extending outward through the door and having a handle at its outer end, in the usual manner. The reverse or unlocking movement of said frame is prevented in the usual manner by connection between. the main lock, 0, and said frame, said lock being usually of the combination type. One of the methods used by burglars for opening a safe or vault door involves the disabling or destroying of the main lock, C, to such extent as to render that look incapable ofholding the bolt frame against reverse movement, the bolt frame being then reversed by means of the handle above-mentioned or by reaching with a tool through the opening made at the lock. Said lock may be disabled by driving the combination stem inward with a hammer, or by drilling holes around the stem, C of the lock until said bolt and associated members may be displaced, or by fusing the metal around the bolt until said bolt and associated parts can be displaced, or by explosion.

My improvement comprises a secondary locking mechanism which is set into the locking position to hold the bolt frame when the main lock has been disabled or destroyed by any such means as are mentioned above. lln the secondary mechanism, D is an anchor bolt. Said bolt extends horizontally through the edge bar, 18 the body of said bolt being screw-threaded into said bar and the cross head, D of said bolt extend ing toward the bolt-carrying bar, B, and being in an upright plane which passes between said bar and the body or the door, B. The opposite end 01? said bolt projects through said bar and the threading on said bolt extends to said end. A. nut, D is threaded on said end and is turned to jam against the outer face of the edge bar when said bolt has been turned to bring it into the desired position. Said jam nut then serves to secure said bolt immovably. l) is a rotary member by means or which the anchor bolt is engaged when the secondary locking mechanism is put into action. The body of the rotary member is disc-form and has at its center a forward-directed. hub, l1), through which and the bar, B, extends a bolt, 1). The head of said bolt is countersunk into said hub, and the bolt has a shoulder, D, which bears against the terward face of the bar, B. Thus the rotary member is held "for free rotation on said bolt, the bolt serving as a journal. Along the periphery of said rotary member is a flange, D which extends nearly around said member, there being a gap large enough to allow the cross-head, D to pass. At one end, said. flange has a slot, D which is parallel to the bar, B", and in the plane of the anchor bolt, D.

Said rotary member is so placed on the bolt-carrying bar, B, as to cause the cross head D of the anchor bolt, D, to pass through the gap in the flange, D and stand in the annular space between said flange and the hub, D when the bolt frame is .iove d into the locking position. long as the rotary member is in this position, the bolt frame may be shifted into and out of the locking position without engagement between the rotary member and the anchor bolt. But when the bolt frame is in the looking position and the cross head oi the anchor bolt is in position in said annular channel in the rotary meml'ier, the rotation of said member in the proper direction to move the channel, D toward the anchor bolt, the parts of the flange, Dear each side of said channel will move astride the bolt, the cross head still remaining in said channel. Then, when eitort is made to reverse the bolt frame out of the locking position, the flange, D will make engagement with the cross head and movement of the bolt frame will be prevented, although the main lock may have been deranged or removed so that it no longer serves to prevent the moving of the bolt frame out or the loel-zing position. The rotary member, D, is turned automatically into its locking posi 'tion by means which will next be described. 011 the bar, B, above the rotary member is a horizontal post, B, into the free end oi which post is driven a screw, D (Figs. 2 and 3) extending through a slot, D, in an oscillating bar, D extending across the rotary member in a plane which is parallel to the plane of the bolt-carrying bar. In the oscillating bar opposite the lower part ot the flange, D is a slot, D A screw, 1), extends through said slot and into said flange and is held immovably. Both of said slots are large enough, and the heads of said screws are sutliciently free from said bar to permit bar to slide endwise on said screws. The screw, D, serves as a wrist on the rotary member, and the rotary member serves as a crank wheel which is to be iven only partial rotation. lating bar, D oscillates with. the screw, D as a ruler-uni. -JVhen said bar is oscillated, the rotary member partially turned :tar enough to cause the flange of the rotary men'iber to engage the cross head, l), of the anchor bolt, D. 'llhe endwise movement of the oscillating bar, D nrovided in order that its lower or tree end may move in a. lit line to adapt it for crmnection with the below-described solenoid core, which is confined to right line moven'ient.

ctangular box, E, is secured to the inner race of the door opposite the rotary member, D and is open toward the interior of the sale and has over the opening a lid, E comprising a :iframe, E and a body of glass, E and hinged to the lower edge of the box. in the lower part of the be): is placed a solenoid base, l l comprising two rectangular compartments, E connected by a web, El. 'lhe uprights walls of the compartments, E have horizontal apertures, Fflwhich are in the same horizontal line, and in. said line is also the lower or free end of the oscillating bar,

ll). (lo the same line each upright wall of the box, ll, has an aperture, ii lnrass tube or bushing, 331, extends thro ertures. i l and 15 and at the outer lace of each oi" said upright boa-z walls said bushing is surround by ring, E whereby said bushir' movement. in said bushing is a solenoid core, E, which is slidable endwise and projects from said tube at one end far enough to n. et and be con E to the lower or rice end oi the os g bar, it). Ad-

n n C u ucent the box, E, the pro ectlng part or the core is screw-threaded and receives a ringform nut, E which may be moved on the core into the desired position to constitute a stop for limiting the movement of the core into the brass bushing, E

When the solenoid core is reciprocated, the oscillating bar is oscillated, whereby the rotary member is partially turned. The main part of the core is steel; but in each compartment, E the solenoid has a short section E, of brass. In each compartment, E the brass bushing, E is surrounded by a wire coil, E One of said coils is wound for moving the core in one direction and the other coil is wound for moving the core in the opposite direction. The coil which controls the movement of the core, E inthe direction for turning the rotary member out of its normal position and into the position for engaging the cross head of the anchor bolt is on an electric circuit which includes a battery and the main lock. mechanism, the circuit being open at the main lock. Between the box, E, and the body, B, of the safe door is a plate of zinc or other conducting metal, E and at each side of said plate is a layer of insulation, E. A screw, E extends through the back wall of the box, E, into the door, B. A bushing, E, of insulation material surrounds said screw in the plate, E whereby the screw is insulated from said plate. The function of said screw is to make electrical connection between the box, IE, and the door, B. Between the body, C, of the main lock and the door is a plate of zinc or similar conducting metal, C, and C are layers of insulation material at each side or the metal plate, (7 An insulation bushing, C, surrounds the stem, (1 of the lock, whereby the plate, insulated from said stem. Above the look, a b in ding screw, C extends through the outer layer of insulation and into the metal plate,

(l Below the box, E, a binding screw, E extends through the outer insulation layer, l5)", and into the metal plate, E, A wire, extends from the binding screw, C to the binding screw, E and thence to said coil, E and thence to the battery, F, and from the battery to the screw, E

' A metal bracket, C, is secured by a screw, C to the metal plate, C said screw extending through the base of the bracket and the adjacent layer of insulation into the plate, Said bracket extends away from the door, parallel to the lower taco of the look, beyond said face and then upward parallel to the rear face of the lock and spaced from said tire far enough to admit a metal plate, U. to be supported by the bracket between the latter and the lock without touching the lock.

At the lock the circuit has now a up or break between the said door, 13, and the metal plate, C and also between the lock and the plate, C of the bracket, or between any part of the bracket and the lock. From the plate, C the circuit extends through the wire, W, and the right hand coil, E and from the coil to the wire, W, to the main battery, F, and from the battery through the wire, W, to the screw, E and through the latter to the door, and through the door to lock stem, C and through said stem to the lock. Drilling through the door around the stem, (l will cause the drill tool, G, (Fig. 9} to touch the door and the metal plate, C in that position, the tool closes the gap or break in the circuit, and the coil, E is then energized :tor shitting the solenoid core, E towar l the right. Burning through the door instead of drilling will destroy the insulation material between the door and the metal plate, C whereby said plate and the door will make contact and close the circuit.

- It the stem, C of the lock is driven inward by hammer blows so as to drive the lock inward, the lock will touch the bracket, C, or the plate, U whereby the circuit will be closed. (See 9.)

When the rotary member has been put into engagement with the anchor bolt through effort by an unauthorized person to derange or destroy the main lock, the other solenoid core is to be energized for retracting the core, E, for reversing the rotary member into its rest position the gap in the flange of the rotary member being brought around. the anchor bolt, so that the rotary member may be carried away by the bolt traniewithout hindrance by the anchor bolt. For the purpose of energizing the second. coil, a circuit is provided which independ: ent of the main lock. At any desired point on the inner face of the body, 1%, oi? the door is placed a metal plate, H, between which and the door is a layer of insulation, H A wire, l l leads from. the platelli, to the second coil and from said coil to the battery and from the battery to the screw, E. a circuit is formed with only a gap between the plate, ll, and the door, said gap being occupied by the layer of insulation, H B now drilling through the door from the outside with a small drill until the plate, H, is touched, said gap is closed by the drill tool. Then the energized second coil draws the core, E away from the free edge oi? the door whereby the rotary member is turned to release itself from the anchor bolt.

While applying the apparatus, the, plate, H, and its layer of insulation, H are put arbitrarily any where on the inner face at the door at place which can be reached with a drill. The chosen location is noted on a chart or diagram which is kept in a secret place ilor reference when it heroines mechanism is attempted, substantially as doscribed.
